Zombie exception

[931743010]

only one number
[yVals1 addObject:[[ChartDataEntry alloc] initWithValue:0 xIndex:j]];

Int(pt.x) exception
BarLineChartViewBase---public var highestVisibleXIndex: Int---Int(pt.x)

[liuxuan30]

mate, you need to provide more info so we can help you. With this I can say nothing

[AntiMoron]

There's an error while doing casting.
just explicitly use BarChartDataEntry instead of ChartDataEntry

[yVals1 addObject:[[BarChartDataEntry alloc] initWithValue:0 xIndex:j]];

to avoid the cast.
I think this is a casting bug.

[931743010]

[yVals1 addObject:[[ChartDataEntry alloc] initWithValue:0 xIndex:j]];
not a casting bug;when server give me one number ;{11:00, 0}
and the andriod version is ok
when my yVals1 only have one number and this number is 0; will have exception
Int(pt.x) exception
exception-site BarLineChartViewBase---public var highestVisibleXIndex: Int---Int(pt.x)

[931743010]

when initWithValue:0 and just one number ; use the LineChartView the pt.x will be {nan,nan}, then will exception.

[liuxuan30]

Well, it should not be nan. There might be something wrong with the data?
Can you reproduce it with ChartsDemo code? Give the full dataSet and reproduce it with ChartsDemo

此贴其实可以中文。

• - 我看 demo是好的， 我再试试

谁知道如何把
里面的日期 竖起来显示呢 如下图

[931743010]

还有 就是柱状图上 x轴显示的 数字是double 能不能 只显示整数，如何做呢

[liuxuan30]

1. use valueFormatter and other available formatters
2. the text rotation is a little complicated, but you could try with CoreGraphics, you can override the renderer

I guess it's better to write in English, as more people can help you.

[AntiMoron]

@liuxuan30 👍

1. Inherit ChartXAxisRenderer and override renderAxisLabels to customize the way labels are rendered.
2. Inherit LineChartView and override its initialize function to reset the xAxisRenderer ;-)

[931743010]

The key is I only know a little about swift，just know about Object-C,my project is write with Object-C. if you have some times off and this is easy for you . Can you write a demo for me,thanks.

[liuxuan30]

I tried rotate the label a little but no luck yet, seems I missed something there.. Maybe it's time to ask for this feature?

[931743010]

Look forward to this function；
i have another question ：
all number Type is int ，but the Axis Display the type of double； is there any Method to display int。
i dont want to Modify the danielgindi/ios-charts.

[931743010]

[AntiMoron]

What you want is exactly what formatters do.

Removal of the decimal number in the X axis of the table
