Gallery of ChIPS examples (Python)

Introductory examples

• Plot two columns from a file
• A radial profile drawn as a histogram
• Contour an image using the WCS axes
• Two curves in a plot
• Multiple histograms within a plot
• Use the sky coordinate system to contour an image
• Placing one plot within another plot
• Plotting related values in a strip chart
• Using a filled region (solid) to show the error bounds
• Filling a region with a pattern to show the error bounds

Basic curves

• A curve marked with symbols and connected by a red line
• A curve marked with diamonds
• A curve connected by a dotted line
• A curve showing the full range of options

Overplotting curves

• Two curves in the same plot
• Two curves in the same plot, one with error bars

Histograms

• Displaying (x,y) data points as a histogram
• Displaying (xlow,xhigh,y) data points as a histogram
• A histogram which shows the bin edges
• A histogram showing the full range of options
• Filling a histogram with a pattern

Contours

• A simple contor plot
• Two sets of contours in the same plot
• Contouring an image using the WCS information

Multiple plots

• Data, fit, and residuals
• Data, residuals, and contours in one frame
• Data and residuals in one frame, contours in another

Sharing an axis between plots

• Three datasets in separate plots with a common axis
• Three datasets in separated plots
• Three datasets in separate plots with a hidden X axis
• A grid where the plots share axes and the plot sizes are different

Error bars

• Symmetric Y errors
• Errors for both the X and Y axes
• A histogram with errors and symbols

Axis styles and grids

• The default plot style is to show all four axes (closed)
• The open plot style only displays two axes
• The boxed plot style draws a box around the plot
• Numeric labels (ticklabels) on all four axes
• Rotating the numbers along an axis
• Changing the format used to display the labels
• Using sexagesimal notation for the axis labels
• Changing the number of major tick marks (using mode=interval)
• Changing the number of major tick marks (using mode=count)
• Displaying a grid at the major tick mark locations
• Add a grid at the major and minor tick mark locations
• Grids work with logarithmically-scaled axes too

Adding axes

• Using a line to indicate an axis
• Adding an extra axis to a plot
• A single plot containing two datasets with a common axis
• Two y axes on the left of the plot

Moving axes

• Moving the axes so they go through (0,0)
• Moving the axes and using a boxed border
• Moving the axes with an open border
