I've been working on it for days and simply cannot make sense of how I can approach it. The problem is the squares are different sizes and I want a pixel for each square represented with the same colour. Coloured image: Coloured image My code for greyscale image: from PIL import Image

For example, I'd want X-axis scale 10 and Y-Axis scale 1. 回答1: You set the TickUnit , if you are using an XYPlot try this XYPlot plot = chart.getXYPlot(); NumberAxis xAxis = (NumberAxis) plot.getDomainAxis(); xAxis.setTickUnit(new NumberTickUnit(10)); NumberAxis yAxis = (NumberAxis) plot.getRangeAxis(); yAxis.setTickUnit(new NumberTickUnit(1)); 文章来源: JFreechart X and Y axis scaling

WinForms Chart: Set minimum Y Axis display range

I like the way the chart works automatically handling the display of the values, but I want to change one simple thing . I want to increase the minimum displayed y axis range, so it displays a range of 20. At the moment it only displays around 5. I have tried a few things: //(when new data arrives...) //Does not work, I think because by default, Size is always NaN? if (chart1.ChartAreas[0].AxisY.ScaleView.Size < 20) { chart1.ChartAreas[0].AxisY

How to change the x axis in Graphite/Grafana (to graph by day)?

由 匿名 (未验证) 提交于 2019-12-03 00:50:01
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I would like to have a bar graph in graphite/grafana that has a single bar per day, over the week. Ideally we would have the days of the week (Monday,Tuesday...etc) on the x axis labels, and then seven bars in the graph, one for each day of the week. I can't seem to change the X axis at all though. Thoughts: I could cook the time data, and send it a fixed time since epoch value, but this results in a very thin bar on the grafana page. I could write a script to send a huge amount of metrics with seconds since epoch values representing the

Thanks 回答1: You should decrease ticks to zero: yourChart.yAxis().ticks(0); Note that this does not return a reference to your chart, so you cannot chain this method. You must put it on a separate line. Like this: var yourChart = dc.barChart('#your-chart').width(1024).height(50); yourChart.yAxis().ticks(0); 回答2: you should decrease ticks for axis yourChart.yAxis().ticks(0);
