Display data

The SPC Chart control generally plots one point for each sample. You can also use the control to plot a chart (IX + MR chart, MA & MR chart, or MA & MS chart) for samples where each result produces a new point. For samples with more than one result, the average is calculated and plotted. Each point in the chart is connected to the next with a line. If the PlotPrimaryMeasurementValues property is set, the measurement values for each point are represented with a different shape on the y-axis.

The sample request time is plotted on the x-axis and the sample value is plotted on the y-axis. If the plotted points do not fit on a single page, a scroll bar appears at the bottom of the control. You can plot two types of charts for the samples — primary charts and secondary charts. The histograms, if displayed, appear to the left of the chart.
