I need your insights on how to visualize/map data that span negative and positive values. I have 6 rasters which have been stacked together ( s ) and will subsequently be plotted via the levelplot function in R. Below are the max and min values for each raster . 39.2887, 53.09207 (min, max) # r1 -32.4956, -27.25534 (min, max)# r2 -14.37683, -11.37742 (min, max)# r3 9.512934, 13.60197 (min, max)# r4 -4.993901, -1.851784 (min, max)# r5 -8.190711, -5.104764 (min, max)# r6 At the moment, I am able to produce my map via: library(raster) library(rasterVis) library(colorRamp) s <- stack(r1,r2,r3,r4

in Tableau I would like to figure out how to combine the y-axes for Former smoker, Never smoked, Smoke everyday, and Smoke some days. I want one y axis that ranges from 0.00 to 1. I appreciate any help, thanks. Not sure your ideal graph output, but instead of plotting each individual measure. Drag the [Measure Values] pill to the y axis and filter for the measures you want. You can then drag [Measure Names] to the color shelf to make a line for each measure. 来源： https://stackoverflow.com/questions/46693583/how-to-combine-the-different-y-axes-into-one-y-axis-in-tableau

I have a dashboard page in which I am using various MSCharts. I have a class defined for each one of these charts, in which I am defining Tooltips of the Series in that chart like below when I run through each chart class and define its Series properties. Series[0].ToolTip = "Date = #VALX{d}\nTotal Qty Shipped = #VALY"; The problem I'm seeing is because there are multiple charts on the page, each with its own chart area. The only chart that shows a tooltip is the first chart that has one assigned to it. The other charts don't show anything even though similar code is run for them. Why does

I'm building a Column chart with System.Web.UI.DataVisualization.Charting and would like to show a dotted line to represent an average. StripeLine seems to be exactly what I'm looking for except it sits under/behind the columns (see example). Is there a way to adjust the "Z-Index" of a StripeLine so that it is shown in front of/on top of the Series ? I don't see a property for this and changing the order I add the Series and StripeLine doesn't make a difference. You can use Annotations double avg = Chart1.Series[0].Points.Average(p => p.XValue); double lineHeight = avg;

I have the following values to be shown in a BAR chart in my Java web application. 9.46373791E8 9.45942547E8 9.45559945E8 9.45187023E8 9.44856693E8 9.44417826E8 9.44007878E8 As u can see the values are really close and have minor differences. When i generate a bar chart using Jfreechart, all the bars appear almost the same height and there is no way of telling the difference visually. So i want to change the (0,0) to (0,9)so that x axis is at number 9 on y axis. I still want to show the real values that the bars represent somewhere on top of the bar. please suggest ideas. i tried the below but

How can I specify colors in heatmap. In this example, the data are uniquely one of 4 values {0,1,2,3} Index= ['aaa', 'bbb', 'ccc', 'ddd', 'eee'] Cols = ['A', 'B', 'C', 'D'] data= [[ 0, 3, 1, 1],[ 0, 1, 1, 1],[ 0, 1, 2, 1],[ 0, 2, 1, 2],[ 0, 1, 1, 1]] print data df = pd.DataFrame(data, index=Index, columns=Cols) heatmap = plt.pcolor(np.array(data)) plt.colorbar(heatmap) plt.show() How can I specifiy those colors in a way to represent colors= {0:'green',1:'red',2:'black',3:'yellow'} Create custom colormap and set ticks to your integers from matplotlib import colors cmap = colors.ListedColormap([

This question has been asked before , but in regards to the old corechart API, which I haven't had a problem with, not the new Material charts. For instance, the following code will create two charts as expected: var data = [ ['Year', 'Sales', 'Expenses', 'Profit'], ['2014', 1000, 400, 200], ['2015', 1170, 460, 250], ['2016', 660, 1120, 300], ['2017', 1030, 540, 350] ]; google.load('visualization', '1', { 'packages': ['corechart'] }); google.setOnLoadCallback(drawChart); function drawChart() { new google.visualization.ColumnChart(document.getElementById('groupedBar')).draw( new google
