ios-charts hide values that are outside the bar bounds (stacked bar chart)

由 余生颓废 提交于 2019-12-08 08:51:09
问题 The values in my charts are currently being rendered outside of their respective bars, how do I make only those values that fit the bars visible? 回答1: This is a known issue, because the sub bar's height is smaller than the value text hight. You can override drawValues to filt those texts. 来源： https://stackoverflow.com/questions/37303049/ios-charts-hide-values-that-are-outside-the-bar-bounds-stacked-bar-chart

由 安稳与你 提交于 2019-12-08 07:26:30
问题 EDITED: This is a debug video as well. I use this library to show charts in my Swift iOS app. This is my chart: X axis is for dates and Y axis is for lifted weight for my athletes. The ocean blue dots in the middle of the charts that you see it is an intersection between a date and lifted weight.

Different colors for bars in BarChart depend on value

由 南笙酒味 提交于 2019-12-07 01:34:51
问题 How can I change the color of a single bar, dependent on its value, in a bar chart? For example: I have five different values (= five different bars) in my bar chart. All bars that have a value less than 30 should be red, all bars between 30 and 70 orange, and all bars above 70 should be green. 回答1: In ios-charts, the colors of the bars are set in an array. If your dataset is called barChartDataset, for example, you would set the colors like this barChartDataset.colors = [UIColor.red,UIColor

iOS-Charts Library: x-axis labels without backing data not showing

由 做~自己de王妃 提交于 2019-12-06 10:15:48
问题 I am using version 3.1.1 of the popular charts library for iOS. I have run into an issue with x-axis labeling that I can't seem to find the answer for online: Let's say I want to have a chart with one x-axis label for every day of the week (namely: S, M, T, W, T, F, S). Lots of forums I've read suggest taking the approach of setting a custom value formatter on the x-axis as suggested here: https://github.com/danielgindi/Charts/issues/1340 This works for calculating labels on days for which I
