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.Points.AddXY(10, 35); S1.Points.AddXY(11, 15); chart1.Series.Add(S1); chart1.Series[0].Points[0]

I am looking for a way to stretch a color gradient between two values and label the legend, regardless of the range of data values in the dataset. Essentially, is there a functional equivalent to ylim() for color gradients? Given code which plots a z value typically between -1 and 1, I can plot and label a gradient if the breaks are within the data range: library(ggplot2) #generator from http://docs.ggplot2.org/current/geom_tile.html pp <- function (n, r = 4) { x <- seq(-r * pi, r * pi, len = n) df <- expand.grid(x = x, y = x) df$r <- sqrt(df$x^2 + df$y^2) df$z <- cos(df$r^2) * exp(-df$r / 6)

I wish to present a distance matrix in an article I am writing, and I am looking for good visualization for it. So far I came across balloon plots (I used it here , but I don't think it will work in this case), heatmaps (here is a nice example , but they don't allow to present the numbers in the table, correct me if I am wrong. Maybe half the table in colors and half with numbers would be cool) and lastly correlation ellipse plots (here is some code and example - which is cool to use a shape, but I am not sure how to use it here). There are also various clustering methods but they will
