问题 I have a chart in WinForms. X-axis is a time line and Y-axis is values are either 0 or 1. How can make the chart display Success/Failure instead of 0 and 1 on Y-axis? 回答1: You can set the Y-axis to use custom labels instead of numbers. chart1.ChartAreas[0].AxisY.CustomLabels.Add(-0.5, 0.5, "Success"); chart1.ChartAreas[0].AxisY.CustomLabels.Add(0.5, 1.5, "Failure"); You have to set a range in which the label will appear. That's why I chose a range from -0.5 to 0.5 for "Success" (it is

Several examples are given in the Developer's guide, available on the project page. Alternatively, you can use jBloomberg* which is simpler to use because it handles the messy details for you. To retrieve historical

问题 When calling axis.setExtremes() or axis.zoom(), the associated zoom button does not become highlighted. For example, if I programatically 'zoom' to 1-hour, I would like the '1 hour' zoom button to appear as 'pressed'. Is there a simple way to accomplish this? For more context: I want to make my app stately, so that if you view a graph, zoom, then navigate away from the graph and back to it again, I want to restore your 'zoom level'. I have this basically working by listening for
