Probably the bug in LazReport.
I have a project which uses lazreport. I would like to print a chart with line series. I have used a method described in demo attached to lazreport components. If the chart is without marks the preview and print are perfect. But, when I turn on the marks, the vertical scale is wrong. For example, my highest point is -0.06 (fig. 1), but in LazReport print preview on the left (vertical axis) the numbers are from 100 to 800. I think that the problem is with TScaledCanvasDrawer. I have tried the second method using PaintOnCanvas and all is OK, however the resolution of print is bad.
