问题 Is there a simple way to remove days with no value? Here is some of my data 12-04-2012 => 15 13-04-2012 => 12 15-04-2012 => 10 16-04-2012 => 5 In chart 14-04-2012 is painted.

问题 My software log some devices parameters and if the device is turned off i want to "interrupt" the series (i think i'll add a special value on the data to highlight a device off) and draw new points only when the device is turned on. I'm using JavaFx LineChart (i don't want to change library) Sorry for my very no talent using paint! 回答1: You should treat each line before and after the break as a new series in the chart. You can keep the colors the same by assigning them to a custom css style

问题 I am working on a scientific calculator in C#. I have the parsing engine and such, now I would like to add a graph so the user can plot a line. Is there any kind of control that will let me input a function and it will graph a line in the chart? I'm not talking about plotting individual points by the way. Take this linear equation in slope-intercept form for instance: f(x) = 2x + 7 The main goal is to allow the user to write 2x + 7 in a textbox, and then it will graph the line. It would be

问题 How do I create a timeline chat which visualizes peoples activities throughout a day in one graph? On the x-axis I plan to place the time. And the y-Axis would be the different persons. First, I thought of a simple stacked bar chart. However, the problem is that Excel would combine all the same activities to one item and don't visualize it on the timeline... I also can't do it by hand as I have several 1000 entries to visualize... I found this post on Stackoverflow, but there there is only

问题 I am trying to add a List to a chart. This list contains a 2 and a 4. foreach (decimal D in numbers) { barChart.Series[0].Points.AddXY(1, D); } It needs to add D to index 1 on the X axis. However, this only outputs 4 rather than six at X1. When it gets to the 4 in the list, it overwrites the 2 that is there, rather than adding to it (making 6). How do I make it add rather than overwrite? EDIT: I did not give enough information apparently. I am using Windows Forms. The chart I am using is in
