StackedBarChart Value on middle of each stacked bar chart

[avjiang]

Hi, very great library!

Btw, how can I set the chart value position on the middle of it?

i try to dig and found this code, but i dont know how to make it appear on the middle of the each barchart. Currently, the value will be displayed on the top of the chart (still inside the chart)

barChartView.drawValueAboveBarEnabled = false

               if dataSet.isDrawValuesEnabled
                        {
                            drawValue(
                                    context: context,
                                    value: formatter.stringForValue(
                                        e.y,
                                        entry: e,
                                        dataSetIndex: dataSetIndex,
                                        viewPortHandler: viewPortHandler),
                                    xPos: x,
                                    yPos: y,
                                    font: valueFont,
                                    align: .center,
                                    color: dataSet.valueTextColorAt(index))
                        }

To clarify, are you asking how to draw a bar's value label in the middle of the bar OR are you asking how to draw all the value labels in the middle of the chart?

hi, what I mean is how to draw a bar's value label in the middle of a bar. so if there is 5 bars in 1 bar chart, the value of 5 bars will be drawn in the middle of each bar. thanks!

I think you already found the right place to override. Just pass the desired y position to draw the labels. use barRect calculation to calculate where is your half bar y position.
