This A contour plot represents a 3-D surface by plotting lines that connect points with common z-values along a slice. Option Sergiy, Yes, -twoway contour- does have some interpolation features but the methods are specific to contour plots (based on cuts of the y-variable rather than dividing the x- and y-variables into smaller pieces). V A basic plot such as a scatter or line plot can be overlaid against a contour plot in Stata to provide extra depth to the data.

I've used 4 levels and I have tried different interpolation methods but they all look the same. Statistical Software Components from Boston College Department of Economics. The appearance of these plots is markedly affected by the I'm not sure what you mean by "a scatter plot including an interaction term and covariates", but perhaps the option -addplot(scatter y x)- is what you are looking for. Contour axes—zscale() The zscale() option is unusual in that it applies not to axes on the plot region, but to the axis that shows the scale of acontour legend. The book begins with an introduction to Stata graphs that includes an overview of graph types, schemes, and options and the process of building a graph. The code seems right (see below). 2008). I've tried to add a white rect(), but i don't quite understand the coordinates as i think the legend key is actually a separate axis or plot.

I do not want to promise an immediate solution, because these graphs are not actually plotting the original data, but a mix of original data and derived Hi Joe, Recently Stata added support for contour plots, I assume there is a similar task there, to smooth the color transitions. contour plot with the legend transparent or blank. If studies appear to be missing in areas of low statistical significance, then it is possible that the asymmetry is due to publication bias. Qty: 1.

Now let's use twoway contour to create a contour plot of the predictions from our model. The articles cover topics ranging from standard and cumulative meta-analysis and forest plots to contour-enhanced funnel plots and nonparametric analysis of publication bias. Note that, for colordiscrete, the level is a point instead of an interval. This type of graph is widely used in many disciplines such as cartography, astrology and meteorology. The command caller contour plot is called contour, however, somewhat strangely, in needs to be called through the 8graph twoway contour— Twoway contour plot with area shading Video example Contour plots in Stata Reference Press, W.

For example, I use ccuts(0(0. That axis is controlled using the c-axis option described in[G-3] axis options. Products Contour-enhanced funnel plots are often used to explore whether the funnel-plot asymmetry is due to publication bias or perhaps some other factors. Also, the In my previous Stata News article, I used graph twoway contour to create a contour plot of the predicted probabilities of hypertension. The call signature for these is nearly identical to that of their two-dimensional counterparts, so you can refer to Simple Line Plots axis choice options associate the plot with a particular y or x axis on the graph; see [ G-3 ] axis choice options . This book debuted as Kindle’s #1 New Release in the category Mathematical & Statistical and continues to appear on Kindle’s best-seller list in numerous categories, including Educational Software and Education Statistics. Contour plots can significantly speed up the process of understanding these coefficients, and presenting the results to others.

Quick start We could use the ccuts() option to draw a contour plot with 7 levels determined by 6 cuts at 7500, 7600, 7700, 7800, 7900, and 8000. The vertical line corresponds to the estimated summary log(RR). It graphs two predictor variables on the x and y axes, and a response variable z as contours. in contour plots, the z dimension with contours are represented using colours or lines. The ccuts() option define that cut values for the correlations while the ccolors defines the colors to be used for each of the cuts. New York: Cambridge University Press.
