Description

Store the zoom/scaling factor and pan coordinates to reopen a closed chart editor keeping its last state (in same TXM session).

Solution

  • create some shared entries in /org.txm.chartsengine.core/src/org/txm/chartsengine/core/preferences/ChartsEnginePreferences.java (like CURRENT_X_PAN, CURRENT_Y_PAN and CURRENT_ZOOM) and sets them as 0 by default
  • update the local result preferences node in pan() and zoom() methods of IChartComponent implementations:
  • /org.txm.chartsengine.jfreechart.rcp/src/org/txm/chartsengine/jfreechart/rcp/themes/base/swing/ItemSelectionJFCChartPanel.java
  • /org.txm.chartsengine.svgbatik.rcp/src/org/txm/chartsengine/svgbatik/rcp/swing/SVGPanel.java
  • in ChartComposite.loadChart() implementations get the value from the local result node if exists otherwise get the default values and pan and zoom programmatically

The system has changed since this issue. JFC charts are cached so the view is restored in a same session. It doesn't apply to R File charts engine and to persistence result reopening but this issue need a more global though about the functionality.
