Charts legend reloading issue

[Sri Vidya]

Hi,

I have upgrade my sencha from 6.0.2 to 6.5.2. When i'm testing graphs functionality, i observed, when i first loaded the chart dynamically, charts and legend functionalities are working fine. But, when i reload i.e when the store data changes, its throwing an error saying 'cannot read property 'getMarkerStyleByIndex' of undefined' in SpriteLegend.js.

here i'm loading the graphs dynamically based on data. And i'm using line and scatter charts.

I'm using setSeries() function to plot.

When I tried plotting using addSeries(), I did not encounter the above error but, the legends are getting added to the current legends for each time i load data, instead of getting overriden.

please provide your suggestions to overcome this.

I have got the same problem

[tlloyduk]

The problem for me was that I was calling setSeries before setStore on the chart, so the series didn't exist in the data when the Legend was drawn and hence the error.

chartStore.setData(data.get('chart').data);
chart.setStore(chartStore);
chart.setSeries(newSeries);

Actually no, this didn't help in all cases... still trying to find the solution other than recreating the entire chart on each reload

I'm having the same problem, and using loadData on charts store to load new data. Chart refreshes fine but not its legend. I tried lengend update method but the make this empty.

Any help will be much appreciated.


Thanks,
