问题 I have one Chart and three ChartArea that are aligned in view, zoom, cursor: this is my related previous post. All things works well except that the three ChartArea are not aligned at the beginning. Following an image of the problem: I think it depends from the digit's number of Y values axis. From some research I try the following configuration: // selezione e zoom dlChart.ChartAreas[VOLTAGE_AREA].CursorX.Interval = 1; dlChart.ChartAreas[VOLTAGE_AREA].CursorX.IsUserEnabled = true; dlChart

问题 How do you create an Annotation on-the-run and how do you enable end-user placement with Annotation.BeginPlacement() ? I've tried to do this in multiple ways, but cannot get it working. It should render itself in real-time after the BeginPlacement() has been called. Documentations on this subject is little to none - and mostly none - so I'm not able to find any help for this problem. What I've tried so far, is to create an annotation and place it with AnchorX/Y, set all Allow- flags to true

问题 I want to add 3 Y-axes for the chart with different scales. I want to get one x axis and different y axis. I did it like below code but I want to show one y axis like in the 2nd image that I attached.. My C# code so far: private void checkBoxUseMultipleYAxis_CheckedChanged(object sender, EventArgs e) { if (checkBoxUseMultipleYAxis.Checked) { // Set custom chart area position chart1.ChartAreas["ChartArea1"].Position = new ElementPosition(25, 10, 68, 85); chart1.ChartAreas["ChartArea1"]

问题 I have a problem with an MS Chart chart type column. If there are more than 9 bars in the chart, the axis-x labels won't show up properly, some of them just disappear. Here's my mark-up for the chart: <asp:Chart ID="chtNBAChampionships" runat="server"> <Series> <asp:Series Name="Championships" YValueType="Int32" Palette="Berry" ChartType="Column" ChartArea="MainChartArea" IsValueShownAsLabel="true"> <Points> <asp:DataPoint AxisLabel="Celtics" YValues="17" /> <asp:DataPoint AxisLabel="Lakers"

问题 My issue is that whenever I add a point to the chart, it compresses all the points. Instead, I want it to auto scroll. Here are two .gifs to explain what my issue is What I have now What I want to achieve The code I have right now is DateTime dt; private void Form1_Load(object sender, EventArgs e) { timer1.Start(); } private void timer1_Tick(object sender, EventArgs e) { dt = DateTime.Now; if (checkBox1.Checked) { chart1.Series["Light"].Points.AddXY(dt.ToShortTimeString(), 1); } else { chart1

问题 I have these XY values: Series S1 = new Series() S1.Points.AddXY(9, 25); S1.Points.AddXY(10, 35); S1.Points.AddXY(11, 15); chart1.Series.Add(S1); but I need to show the X values in the graph like this: X="9-10" X="10-11" X="11-12" How can I achieve that? So far this is what I've found: and here is the code: private void Form1_Shown(object sender, EventArgs e) { chart1.ChartAreas[0].AxisX.Minimum = 7; chart1.ChartAreas[0].AxisX.Maximum = 15; Series S1 = new Series(); S1.Points.AddXY(9, 25); S1

问题 why is it that the MS chart rectangular annotation width is in percent and not pixel like msdn says it is? https://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.annotation.width(v=vs.110).aspx This is what msdn says Gets or sets the width, in pixels, of an annotation. I'd like to set my width to be pixels like it states. Am I missing something here? 回答1: Congratulations, you have found a bug in the documentation! Easy to spot simply by following the link to

问题 I use Image from Resources to LegendItem in WinForms var ImageName = "ImageName"; myChart.Images.Add(new NamedImage(ImageName, Resources.Image)); LegendItem legendItem = new LegendItem(); legendItem.Name = "legend text"; legendItem.Image = ImageName; myChart.Legends[Legend.Name].CustomItems.Add(legendItem); But the size of Image is too small. How can I change it? 回答1: You should use custom LegendCell in this case. This means you define the cells for your LegendItem specifying their properties

问题 I have an ASP Chart like this: I am not sure how I can make the labels for the values to appear vertical instead of being horizontal. I am not sure if this can be achieved by CSS as the resultant output is an image. All I have with me is the code which says something like this: Saw some similar question here: C# chart rotate labels, but it is for C# and the given solution has C# code. I am using ASP.NET VBScript and also I am not using any code other than the above mark-up. Also please advice

问题 i'm currently running into issues with MSChart, esp. a BarChart. The chart is meant to be exported and saved into an image file and has a huge amount of seperate bars to be shown, resulting in a height of 38960px. The problem: It seems like the height of the axis' label is calculated percentual with a minimum of 1 (and again with a minimum of 10px afterwards). This way the label is about 390px away from the chart ... To illustrate the issue, i set AxisX.Crossing = 0, so the axis should be
