hi,see me again :)

As you can see the first image,it's when it load first time.so what can i do to showing all the XAxes labes as the second image showing.

THX a lot. +1:

By the way ,checked value of the first subcolumn may be covered by the Y Axis sometimes.

Hi, try to modify maxLabelChars attribute for X axis, for example set it to value 1:

axisX.setMaxLabelChars(1);

Hi ,I tried to modify part of your source code, and it works now.Here it is.
I modified method "calculateMaxViewport() : tempMaximumViewport.set(-1.1f, baseValue, data.getColumns().size() - 0.5f, baseValue);" and method "calculateMaxViewportForSubcolumns : tempMaximumViewport.top = (float) columnValue.getValue()*1.2f;" ,and here are they in ColumnChartRenderer.java:

private void calculateMaxViewport() {
final ColumnChartData data = dataProvider.getColumnChartData();
// Column chart always has X values from 0 to numColumns-1, to add some
// margin on the left and right I added
// extra 0.5 to the each side, that margins will be negative scaled
// according to number of columns, so for more
// columns there will be less margin.
tempMaximumViewport.set(-1.1f, baseValue, data.getColumns().size() - 0.5f, baseValue);
if (data.isStacked()) {
calculateMaxViewportForStacked(data);
} else {
calculateMaxViewportForSubcolumns(data);
}
}

private void calculateMaxViewportForSubcolumns(ColumnChartData data) {
    for (Column column : data.getColumns()) {
        for (SubcolumnValue columnValue : column.getValues()) {
            if (columnValue.getValue() >= baseValue && columnValue.getValue() > tempMaximumViewport.top) {
                tempMaximumViewport.top = (float) columnValue.getValue()*1.2f;
            }
            if (columnValue.getValue() < baseValue && columnValue.getValue() < tempMaximumViewport.bottom) {
                tempMaximumViewport.bottom = (float) columnValue.getValue();
            }
        }
    }
}

@wangyg1990 怎么设置x轴文字竖排？

Y 轴是怎么显示100000这样很长的数据的？

Thanks, saved me lots of time
