The following charts have Plot lines/Reference lines feature: line, area, sparkline, bar, column, stacked bar, stacked column, bullet, tornado, column range, slope, dumbbell, bubble and histogram charts.
Go to the ‘Plot Lines’ tab in the property editor window and select the metric based on which you want to draw plotline in the ‘source’ drop down window.
Apply the conditions like min, max, avg, first, last, and percentile. Apart from these fixed conditions, you can give a particular value as input at which you want to draw a plot line. You can apply colors to plot line, change the plot line width, change the style of the line and title to the plot line. At last click on the ‘Apply’ button.
In 3.8 release, support for plotlines on the vertical axis is added in the bubble chart. Please refer the below screenshot showing plot lines/reference lines on both the horizontal and vertical axes.
Plot lines/Reference lines can be used in the ‘source’ field in thresholds.
Once we set the plot line in any Vitara chart, the name of the plot line will show up in the source field of the thresholds tab. We can set plot lines as a source in the thresholds. When we set a plot line as ‘Source’ in a threshold we can apply the condition ‘Above the line’ or ‘Below the line’ in the threshold.
Below is a screenshot of bubble chart in which two thresholds are applied based on the plotline “Plot line1: Avg of Revenue”. The first threshold is based on the condition ‘above the plotline set bubble color as the green color’ and in the second threshold ‘below the plotline set bubble color as red.’
