Data Charts

Data charts allow you to graphically represent the data obtained from measurements or otherwise. Data charts are linked to corresponding Data tables or the Global Grid. You can select several types of charts and adjust their appearance. To open a Chart document for linked to a table, select the data of interest in the table and click the Chart button on the toolbar at the top of the frame. The Chart window will appear:

Click the Data Series tab to select the data series to be plotted. Choose among the following options:

Parameters

Lets you select the parameter representing the data series to be plotted. The list will display all parameters available in the table from which the chart was originated.

Class

Lets you select the class ID representing the data series to be plotted. The list will display all class IDs available in the table from which the chart was originated. Click All to disregard the classification of objects.

Add

Click this button to add the currently selected parameter and class ID to the Data series grid.

Data series grid

Lists the measurement parameters and objects' class IDs that will be plotted. The data series are plotted in the order from top to bottom. The amount of data series used depends on the type of the graph selected. For the Bar Histogram, Line Histogram, and Pie Diagram only the first data series is plotted. The Scattegram and 3D-Histogram use the first and second data series. The Multi-histogram plots all data series next to each other.

Remove

Click this button to remove the highlighted data series from the Data series grid.

Up

Click this button to move the highlighted series to the previous row of the Data series grid.

Down

Click this button to move the highlighted data series to the next row of the Data series grid.

Clear

Click this button to clear the entire content of the Data series grid.

Click the Option tab to change the type of the graph and adjust its appearance. Chose among the following options:

Graph type

Lets you select the desired graphic representation of the data selected. Choose one of the following types:

Bar Histogram

Select this mode to plot the measurement data in form of bar histogram. Measurement histograms illustrate the distribution of your object population over a measurement range. The histogram's X-scale identifies the parameter's range (from its minimum value to its maximum value), and the Y-scale measures the number of objects within each measured interval. Data values in the bar histogram are represented by vertical bars.

Line Histogram

Select this mode to plot the measurement data in form of line histogram. Analogous to the bar histogram except that data values in the line histogram are represented by connected straight-line segments.

Pie Diagram

Select this mode to plot the measurements data in form of round diagram. The round diagram displays the distribution of the selected parameter among the measured parameter's range. The segments of the diagram correspond to the percentage of objects within each measured interval.

3D-histogram

Select this mode to plot two measurements in form of 3D-histogram, where the X1-axis represent the value of the first parameter in the Data series grid, the X2-axis represents the value of the second parameter, and the Y-axis measures the number of objects with the values of both parameters falling within corresponding intervals. Data values in the bar histogram are represented by vertical pillars.

Scattergram

Select this mode to plot two measurements against each other. Scattergrams are used to illustrate a correlation between two measurements. ImageWarp displays the scattergram along with its correlation factor and the best-fit line drawn through the points. In order for the scattergram to be displayd, the Data series grid must contain at least two series.

Multi-histogram

Select this mode to plot the histograms of several measurements next to each other in a 3D-form. X-axis represents the data series selected into the Data series grid, the X2-axis serves as a divider between different data series, and the Y-axis represents the number of objects within each interval. Data values in the multi-histogram are represented by vertical pillars.

Chart title

Lets you change the descriptive text displayed at the top of the plotting area of the Chart. By default ImageWarp assigns the chart title depending on a currently selected type of the graph. Enter a different string if you want to change the chart title.

Parameter (X) title

Lets you change the descriptive text displayed along the X-axis of the Chart. By default ImageWarp sets it to a string containing the name of the parameter taken from the first data series and the corresponding measurement unit. Enter a different string if you want to change the parameter title.

Second parameter (X2) title

Lets you change the descriptive text displayed along the X2-axis of the 3D-histogram. By default ImageWarp sets it to a string containing the name of the parameter taken from the second data series and the corresponding measurement unit. Enter a different string if you want to change the second parameter title.

Value (Y) title

Lets you change the descriptive text displayed along the Y-axis of the Chart. By default ImageWarp assigns the value title depending on a currently selected type of the graph. Enter a different string if you want to change the value title.

Classes (X)

Lets you select the number of intervals into which the measured parameter's range will be divided. This corresponds to the number of classes displayed along the X-axis of the histogram graphs or number of segments in the Pie diagram. The option is unavailable for the Scattergram.

Classes (X2)

Lets you select the number of intervals into which the range of values of the second parameter will be divided. This corresponds to the number of classes displayed along the X2-axis of the 3D-histogram. The option is unavailable for all other types of graphs.

X-axis, Y-axis

Select these check boxes if you want the horizontal and/or vertical axis to be displayed on the chart. An axis is the line that borders one side of the plot area providing a frame of reference for measurements or comparison in a chart. These options are unavailable for the Pie diagram, Scattergram and 3D-hisgoram.

X-ticks, Y-ticks

Select these check boxes if you want the horizontal and/or vertical tick marks to be displayed on the chart. Tick marks are small lines of measurements, similar to divisions on a ruler that intersect axes. Tick-marks are labeled with numbers that identify the values in the chart. These options are unavailable for the Pie diagram.

X-grid, Y-grid

Select these check boxes if you want the horizontal and/or vertical gridlines to be displayed on the chart. Gridlines are lines that extend from the tick marks on an axis across the plot area and make it easier to view and evaluate data. These options are unavailable for the Pie diagram.

Logarithmic scale

Select these check boxes to switch the X- or/and Y-axis display to a logarithmic scale. Use of a logarithmic scale will enhance the display of low values if there is a wide dynamic range to the object's count or parameter's value.

Wall

Select this check box to add the gray shadow to the vertical plane(s) of the chart.

Floor

Select this check box to add the gray shadow to the horizontal plane of the 3D-hisgoram and Multi-histogram. This option is unavailable for other types of graphs.

Legend

Select this check box to display the legend next to the graph. A legend is a box that identifies colors assigned to different classes on the Pie diagram or different data series on the Multi-histogram. For other types of graphs this option is unavailable.

Point marks

Select this check box to mark data values with points on the Line Histogram and Scattergram. For other types of graphs this option is unavailable.

3D angle

Lets you adjust the perspective of the 3D-Histogram and Multi-histogram by entering the angle between the X2 axis and horizontal in degrees.

Fitting

Select this check box to display the best-fit line on the Scattergram.

Power

Select the power of the polynom to be used to build the best-fit line for the Scattergram.

Gaussian

Select this check box to display a Gaussian curve on the histogram chart. The Gaussian represents a normal distribution with the same mean and standard deviation that the plotted measurement parameter has. This option is available only for the Bar and Line Histogram.

Cumulative

Select this check box to display the histogram in a cumulative form. Each bin of the cumulative histogram contains a number of objects that have a marked or lesser value of the measurement parameter. This option is available only for the Bar and Line Histogram.

Weighted

Select this check box to display the histogram in a weighted form. In the weighted histogram a number of objects that fall into each bin is multiplied by an average parameter's value for this bin. The Y-axis represents the "weight" of objects belonging to a corresponding range of the measurement parameter. This option is available only for the Bar and Line Histogram.

Click the Chart tab to display the chart in a full size window.
Like any window, a Chart window can be moved and resized. To move a data table, drag its title bar. To resize a data table, drag its borders. The graph will be resized proportionally to match the frame size.
