Using Y-axis values per serie in the chart
Each serie in the chart can have its own Y-axis values. It can be choosen if the Y-axis values for a series should be displayed left or right from the chart. The settings to control this are under Serie.YAxis.Position. When two series have an Y-axis displayed on the same size of the chart, the spacing between the Y-axis itself and value is controlled by Serie.YAxis.MajorUnitSpacing := 30;
In the code sample below, 4 series are added to the chart. Series 1 and 3 have the Y-axis on the left side while series 2 and 4 have the Y-axis on the right side. To make clear what Y-axis belongs to what series, the serie line color is set to the same color as the Y-axis value font.
