This tab of the Preferences dialog box lets you adjust the general settings related to the default appearance of the Charts


Lets you select the default type of the charts. 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 Xscale identifies the parameter's range (from its minimum value to its maximum value), and the Yscale 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 straightline 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.


3Dhistogram


Select this mode to plot two measurements in form of 3Dhistogram, where the X1axis represent the value of the first parameter in the Data series grid, the X2axis represents the value of the second parameter, and the Yaxis 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 bestfit line drawn through the points. In order for the scattergram to be displayd, the Data series grid must contain at least two series.


Multihistogram


Select this mode to plot the histograms of several measurements next to each other in a 3Dform. Xaxis represents the data series selected into the Data series grid, the X2axis serves as a divider between different data series, and the Yaxis represents the number of objects within each interval. Data values in the multihistogram are represented by vertical pillars.


Default value: Bar Histogram



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 Xaxis of the histogram graphs or number of segments in the Pie diagram. The option is unavailable for the Scattergram.


Default value: 15



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 X2axis of the 3Dhistogram. The option is unavailable for all other types of graphs.


Default value: 5



Lets you select the type of the bestfit line for the Scattergrams. Choose one of the following options:


None


Select this mode to disable the bestfit line.


Connect


Select this mode to connect data points with straight segments in the order of appearance.


Polynom


Select this mode to plot the bestfit line based on the polynomial equation using the leastsquares method.


Default value: Polynom


Power


Select the power of the polynom to be used to build the bestfit line for the Scattergrams.


Default value: 1


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.


Default value: Disabled



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.


Default value: Disabled



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 Yaxis 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.


Default value: Disabled



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 3Dhisgoram.


Default value: Enabled



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. Tickmarks are labeled with numbers that identify the values in the chart. These options are unavailable for the Pie diagram.


Default value: Enabled



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.


Default value: Enabled



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


Default value: Enabled



Select this check box to add the gray shadow to the horizontal plane of the 3Dhisgoram and Multihistogram. This option is unavailable for other types of graphs.


Default value: Enabled



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 diagrams or different data series on the Multihistograms. For other types of graphs this option is unavailable.


Default value: Enabled



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


Default value: Enabled



Lets you adjust the perspective of the 3DHistograms and Multihistograms by entering the angle between the X2 axis and horizontal in degrees.


Default value: 45
