Graph Position properties

Use the graph position properties to specify settings, as a factor of the total control width or height, that define the left, right, and bottom margins of the SPC Control chart graphic within the control. If the table is shown, it will also adjust based on these position properties. These are design-time and run-time properties.

You can use these properties to reduce white space in the chart display. For example, if the chart does not include frequency histograms on the left (by default, they take up about 20% of the available chart width), you may want to adjust the location of the start (left side) of the graph to be closer to the edge of the control. (For information about not including the histograms, see ShowPrimaryHistogram property and ShowSecondaryHistogram property.)

You cannot set these properties to Null.

The available graph position properties are described in the following table. All graph position properties have a range of 0 to 1

The following figure indicates to what edges of the graph the position properties apply.

Note that the sides of the graph are considered to begin and end with the grid, and do not take into account labels that might display outside of the graph grid. Therefore, use care when adjusting these settings:

• Too small a value for GraphStartX will cause the chart to overlap with the histogram or will cause the values in the table to overlap with the labels.

• Too large a value for GraphStopPosX will cause the control line labels to be lost off the right-side of the control.

• Too large a value for GraphBottomPos will cause the x-axis labels to be lost off the bottom of the control.
