问题 I need to set a static width of a bar chart series using dotNetCharting. My Graph has three series collections of line, spline, and column type. I would just like to set a static width for all series of column type. I've tried using: myChart.DefaultAxis.StaticColumnWidth = 10; But the .DefaultAxis property isn't valid in intellisense for the whole chart nor the Column series collection. Do the series have to be added with data first before setting this? Also, I've tried adding properties in

NVD3 - configuring ticks on axis

由 痴心易碎 提交于 2019-12-23 15:43:20
问题 I have a nvd3 line chart which displays a time series and can't get the ticks on the x axis right. For longer time spans, it works as expected. But for shorter time spans (here: 12/31/05 to 01/01/06), the same date is displayed for multiple ticks: Please have a look at the code for this chart on JSFiddle I want the chart to only display ticks at data points, and not in between. Is that possible with a line chart? From my understanding, it is possible with d3, but I can't figure out if this

由 一世执手 提交于 2019-12-23 14:56:43
