dojo - memory leak in a chart create/render/destroy cycle -



dojo - memory leak in a chart create/render/destroy cycle -

i have basic chart2d question. isn't chart.destroy() supposed remove , clean-up memory? if yes, why next code becomes memory hog? please note won't see chart because it's destroyed instantly. using google chrome's task manager @ memory usage, , after 20 minutes goes beyond 200mb.

i know updateseries(), that's not want, graph properties may alter in each iteration (title, axes, plots, data, colors, etc.), figured easiest way destroy chart , recreate again. , if there improve way solve problem i wondering what's best way rid of chart , memory bindings?

one side note: if remove addplot, addaxis, , addseries lines (so new, render, , destroy left), you'd still same, high memory usage. also, using 1.8.0.

thanks,

not sure if help, give try:

chart1.destroy(); delete chart1;

memory-leaks dojo dojox.charting
