Fitted 'glmnet' model. What is on the X-axis. 'norm' plots against the L1-norm of the coefficients, 'lambda' against the log-lambda sequence, and 'dev' against the percent deviance explained. If TRUE, label the curves with variable sequence numbers. Other graphical parameters to plot.
Up:Plot Commands- These examples show how to plot univariate and multivariate time series data by using the Econometric Modeler app. After plotting time series, you can interact with the plots. Plot Univariate Time Series Data. This example shows how to plot univariate time series data, then overlay recession bands in the plot.
- Pdemesh (model) plots the mesh contained in a 2-D or 3-D model object of type PDEModel.
Note: If you were working in SPSS (or for some other reason you have run a model but can’t generate a plot for it), you can enter in your coefficients here, like this: b0. For Stan-models, plots the prior versus posterior samples. For linear (mixed) models, plots for multicollinearity-check (Variance Inflation Factors), QQ-plots, checks for normal distribution of residuals and homoscedasticity (constant variance of residuals) are shown. For generalized linear mixed models, returns the QQ-plot for random effects.

<plot type> is a keyword describing the various plots allowed. Up to six plot panes can be put on a single page by combining multiple <plot type> options. For example:will produce a 4-pane plot. However contour plots may not be combined with other plots in this manner. When a certain plot type takes additional arguments (eg. chain, model), simply list them in order prior to specifying the next plot type:In multi-pane plots, XSPEC will determine if two consecutive plot types may share a common X-axis (e.g. plot data delchi, or plot counts ratio). If so, the first pane will be stacked directly on top of the second. (Note that the small subset of multi-pane plots that were allowed in earlier versions of XSPEC all belonged in this category.)
For changing plot units, see setplot energy and setplot wave. Also see iplot for performing interactive plots.
When plotting colors the ordering is from pgplot and is shown in Figure 5.1.
Plot only the background spectra (with folded model, if defined). To plot both the data and background spectra, use plot data with the setplot background option.
Plot a Monte Carlo Markov chain.
plot chain [thin <n>] [mean] [auto <n>] <par1>[<par2>]
Plots Modeler Magazine
Chains must be currently loaded (see chain command), and<par1> and <par2> are parameter identifiers of the form[<model name>:]<n> or for response parameters[<source number>:]r<n> where <n> is aninteger, specifying the parameter columns in the chain file to serveas the X and Y axes respectively. To select the fit-statistic column,enter '0' for the <par> value. If <par2> is omitted,<par1> is simply plotted against row number.
Use the thin<n> option to display only 1 out of every <n> chain points. Example:The thin value will be retained for future chain plots until it is reset. Enter thin 1 to remove thinning.
Use the mean option to display the running mean based on allprevious chain values instead of the chain value.
Use the auto<n> option to display the autocorrelationfunction for the chain where <n> is the number of lags toplot. auto cannot be used at the same time as meanand it will ignore the setting of thin. auto onlyuses one parameter identifier. For example:
Plot contributions to chisq. The contribution is plotted +ve or -ve depending on whether the residual is +ve or -ve.
Plot the results of the last steppar run. If this was over one parameter then a plot of statistic versus parameter value is produced while a steppar over two parameters results in a fit-statistic contour plot.
plot contour [<min fit stat>[<# levels>[<levels>]]]
where <min fit stat> is the minimum fit statistic relative to which the delta fit statistic is calculated, <# levels> is the number of contour levels to use and <levels> := <level1> ... <levelN> are the contour levels in the delta fit statistic. contour will plot the fit statistic grid calculated by the last steppar command (which should have gridded on two parameters). A small plus sign '+' will be drawn on the plot at the parameter values corresponding to the minimum found by the most recent fit.
The fit statistic confidence contours are often drawn based on a relatively small grid (i.e., 5x5). To understand fully what these plots are telling you, it is useful to know a couple of points concerning how the software chooses the location of the contour lines. The contour plot is drawn based only on the information contained in the sample grid. For example, if the minimum fit statistic occurs when parameter 1 equals 2.25 and you use steppar 1 1.0 5.0 4, then the grid values closest to the minimum are 2.0 and 3.0. This could mean that there are no grid points where delta-fit statistic is less than your lowest level (which defaults to 1.0). As a result, the lowest contour will not be drawn. This effect can be minimized by always selecting a steppar range that causes XSPEC to step very close to the true minima.
For the above example, using steppar 1 1.25 5.25 4, would have been a better selection. The location of a contour line between grid points is designated using a linear interpolation. Since the fit statistic surface is often quadratic, a linear interpolation will result in the lines being drawn inside the true location of the contour. The combination of this and the previous effect sometimes will result in the minimum found by the fit command lying outside the region enclosed by the lowest contour level.
A grey-scale image of the data being contoured is also plotted. Thiscan be removed by using the PLT command image off.

Plots Modeler Lines
Plot the residuals in terms of sigmas with error bars of size one. In the case of the cstat and related statistics this plots (data-model)/error where error is calculated as the square root of the model predicted number of counts. Note that in this case this is not the same ascontributions to the statistic.
Plot a histogram of the relative contributions of plasma at differenttemperatures for multi-temperature models. This is not very clever atthe moment and only plots the last model calculated.
