Tag: memoryDebugMode

I updated schichart to the very last version and turn on the memory usage debug mode to see if there are any memory leaks in our application and ran into the following problem.

When MemoryUsageHelper.isMemoryUsageDebugEnabled = true; and sciChartSurface has the following modifiers(RolloverModifier, CursorModifier) when moving the mouse over the chart I have the following console warnings.

From RolloverModifier instance

From CursorModifier instance

The message below is written on your docs about debugging, so I gues this is the case with the chart modifiers console warnings.

Usually this boils down to failing to call SciChartSurface.delete() (or series.delete(), annotation.delete() when adding/removing objects) or plain JavaScript memory leaks where references to SciChart are held in the customer application & not garbage collected by the browser.

Steps To Reproduce

1. Follow the codesandbox example by the link https://codesandbox.io/s/ts-band-chart-xwlxcm?file=/src/App.tsx;
2. Once the chart is loaded and rendered, try moving the mouse cursor over the chart;
3. Open the browser console ⇒ You will see the warnings I wrote about above.

The current behavior

Moving the mouse over the chart causes warning logs to appear in the browser console and possibly memory leaks.

The expected behavior

No warning logs while moving the mouse over the chart.
