negative y value overlay with x labels

[liuxuan30]

Reproducible with ChartsDemo,

Just use negative values for a bar chart:

[yVals addObject:[[BarChartDataEntry alloc] initWithValue:-val xIndex:i]];

I second that!

Well I guess it's not as easy as it looks like. The label will always take up some space.. you could turn it off or add some offset for it to work around it for now.

@liuxuan30 Can we have marker popup shown only for negative bars, as I want to hide negative bar values to avoid overlapping but positive bar values doesn't have overlapping problem as I don't have right y axis labels?

[liuxuan30]

Of couse you can, but you have to write your own code, it does not support this by default.

I moved negative bar values to top and right aligned, fixed bar space to accommodate values just above bar:
Changes made to HorizontalBarChartRenderer
Added at line 320:
re-align negative values to avoid overlapping with y axis
var xPos = valuePoints[j].x + (val >= 0.0 ? posOffset : negOffset)
var yPos = valuePoints[j].y + yOffset

                    if val < 0 {
                        xPos = xPos + valueTextWidth + 2
                        yPos = yPos - 15
                    }

                    drawValue(
                        context: context,
                        value: valueText,
                        xPos: xPos,
                        yPos: yPos,
                        font: valueFont,
                        align: textAlign,
                        color: valueTextColor)

Hope this helps someone desperate to get it fixed:

Well done! - Closing

[liuxuan30]

reopen as the issue is not resolved. I mistakenly closed it.
Still, a solution is needed how we draw text if there are overlap.

Really? Still open?

Workaround: xAxis.yOffset = 10
