A Typical Hi-Lo-Close Plot
Some data series are best represented by their range at each time-value. Temperature data is typical – here the most informative chart shows the maximum and minimum values by day, with the range drawn as a vertical line. This chart is also commonly used for stock-price data where the daily high and low may be combined with opening and closing values to produce a wide variety of typical ‘Wall Street Journal’ plots of the market data.
There are many variations on this chart, but most of them come down to a combination of a MinMax and an overlayed scatterplot. The ‘LeftTick’ and ‘RightTick’ markers are specifically designed for this type of chart – you could additionally use a LeftTick to show the opening level if required.
SharpPlot sp = new SharpPlot();
hi = new int[] {123,118,119,125,132,135,140,141,138,136,131,132};
lo = new int[] {120,115,117,123,128,134,135,136,131,125,122,125};
close = new int[] {122,116,117,124,129,135,139,141,132,130,124,126};
wkno = new int[] {36,37,38,39,40,41,42,43,44,45,46,47};
sp.Heading = "Hi-Lo Close Chart";
sp.SetPenWidths(2);
sp.DrawMinMaxChart(hi,lo,wkno); // SharpPlot.DrawMinMaxChart
sp.SetMarkers(MarkerStyle.TickRight);
sp.LineGraphStyle = LineGraphStyles.Markers|LineGraphStyles.NoLines;
sp.DrawLineGraph(close,wkno);
