Chart update problem

[ly678910]

Versions 0.5.11 and 0.6.0 show blank space when data is updated to the empty array dataSets. No no data prompt is displayed. And when your finger moves the vertical dotted line on the chart, the app flashes back with an error when the dataSets data is updated. Please deal with the author, thank you

We are line charts with a large amount of data

In fact, when there is data update to no data, the display is blank, and the default no chart data available should be displayed

It has to do with the index of the dotted line
