Current Behavior: When you zoom in repeatedly on the chart, Sierra Chart only remembers the very first zoom level. Pressing zoom-out always returns you to that initial view, even if you’ve performed multiple zoom-in steps. Desired Behavior: Treat each zoom-in as a step in a history stack. On zoom-out, first return to the view you had immediately before your most recent zoom-in. Subsequent zoom-outs should step back through your zoom history one level at a time—just like an undo stack for zoom. I want to implement this using ACSIL but I need to know the alogrithm/calculation done by Zoom in tool I can use: ACSIL Interface Members - Variables and Arrays: sc.ScrollToDateTime but then I need to know by how many pixels to increase ACSIL Interface Members - Variables and Arrays: sc.ChartBarSpacing so the selected range of bars fits nicely Thank you. |
