c# - Misalignment of two chart areas -
i trying overlap 2 chart areas. share same x values, y have different values , scales.
here outcome of code:
as can see red series not in alignment green series.i searching site answers, couldn't find 1 worked. explain me why don't align?
code:
using system; using system.drawing; using system.windows.forms; using system.windows.forms.datavisualization.charting; namespace testgraph { public partial class form1 : form { public form1() { initializecomponent(); #region data // creating first series series s1 = new series(); s1.name = "values"; s1.charttype = seriescharttype.column; s1.xvaluetype = chartvaluetype.datetime; s1.color = color.green; s1.borderwidth = 2; // hard coding test values datapoint[] values = { new datapoint(new datetime(2017, 8, 1).tooadate(), 10), new datapoint(new datetime(2017, 8, 2).tooadate(), 11), new datapoint(new datetime(2017, 8, 3).tooadate(), 12), new datapoint(new datetime(2017, 8, 4).tooadate(), 13), }; // adding vales s1 foreach (datapoint p in values) { s1.points.add(p); } // creating second series series s2 = new series(); s2.name = "values 2"; s2.charttype = seriescharttype.column; s2.xvaluetype = chartvaluetype.datetime; s2.color = color.red; s2.borderwidth = 2; // hard coding test values datapoint[] values2 = { new datapoint(new datetime(2017, 8, 1).tooadate(), 0.1), new datapoint(new datetime(2017, 8, 2).tooadate(), -0.2), new datapoint(new datetime(2017, 8, 3).tooadate(), -0.7), new datapoint(new datetime(2017, 8, 4).tooadate(), 13), }; // adding vales s2 foreach (datapoint p in values2) { s2.points.add(p); } #endregion #region charts // initializing chart chart mainchart = new chart(); chartarea area = new chartarea(); chartarea area2 = new chartarea(); controls.add(mainchart); mainchart.dock = dockstyle.fill; // adding areas mainchart mainchart.chartareas.add(area); mainchart.chartareas.add(area2); // adding series areas s1.chartarea = area.name; s2.chartarea = area2.name; mainchart.series.add(s1); mainchart.series.add(s2); // aligning areas // overlapping area2 area area2.alignmentstyle = areaalignmentstyles.all; area2.alignmentorientation = areaalignmentorientations.all; area2.alignwithchartarea = area.name; // scale actualization area2.recalculateaxesscale(); area.recalculateaxesscale(); // defining y scale area2.axisy.maximum = 2; area2.axisy.minimum = -2; area2.backcolor = color.transparent; // disabling unnecessary graphics area2.backgradientstyle = gradientstyle.none; area2.axisx.ismarginvisible = false; area2.axisx.labelstyle.enabled = false; area2.axisy.labelstyle.enabled = false; area2.axisx.enabled = axisenabled.false; area2.axisy.enabled = axisenabled.false; // resizing chart 100% area.position = new elementposition(0, 0, 100, 100); #endregion } } }
one of chart has axisx.ismarginvisible set true, other false, hence mismatch.
however, if trying plot overlapping series, why not adding them same chart area instead of going through trouble?
