In this tutorial, we're going to cover some more customization, along the lines of colors and fills. Next, we can specify specific numbers for our axis to show, rather than automated choices like so:.

Next, I would like to cover fills. What fills does is it will fill between the variable and a number you can choose. For example, we can do something like:. One problem with fills, is that we might wind up covering things up.

We can solve this with an alpha:. Now, let's talk about conditional fills. Let's assume the start the graph is where we started buying into eBay. From here, if the price goes below this price, we can fill up to the original price and then if it goes above, we can fill below. We can do this by:. No problem! We can add a where parameter, like so:.

Here, we are filling between the current price, and the original price, where the current price is above the original first price. We give it a face color of green, since this is a rise, and we apply a slight alpha. We still cannot apply a label to polygon data like fills, but we can implement empty lines like before, so we can do:. This gives us our fills, and a couple empty lines to handle for the labels that we want to show up in the legend.

At this point, the full code is:. The next tutorial: Spines and Horizontal Lines with Matplotlib. Colors and Fills with Matplotlib.I'd like to create ellipses in matplotlib with a fill color that has an alpha opacity value that depends on the radius. I don't think matplotlib currently supports gradient fills for patches - see this email.

Is there an easy way to do this in matplotlib? There is no support for this currently -- it wouldn't be too hard to add for backends that support this kind of thing. Basically, we need to specify the API for it, and add support to backends.

I have been wanting to add gradient fills for patches eg polygons, rectangles and it would be good to do both at once. Instead of using patches you could create a mesh, calculate the colours with a function then use imshow with interpolation:.

Unfortunately, there is no simple way, as MPL does not support gradient yet.

There is a hard way though, that you create a gradient image by yourself and clip it with the appropriate path. I guess, the easiest way for a normal user is to export the figure as the SVG format and put some gradient using inkscape, or similar tools.As Figure 1, you will see that the green beam has more stress at element 3 and also element 8 Thus if i fill the color by rainbow gradient,The over all of blue beam will be same color but The green beam will have different color by the element 3 and 8 will be going to red side more than others.

I have accessed data from twitter using tweepy in python and I have stored it in a text fileThe text file contains tweets from 30 twitter handles and is inverted comma separated. I try to plot stress of beam by using matplotlib library. I have calculated by using formulas and plot it for an example: As Figure 1, you will see that the green beam has more stress at element 3 and also element 8 Thus if i fill the color by rainbow gradient,The over all of blue beam will be same color but The green beam will have different color by the element 3 and 8 will be going to red side more than others.

Here is some of my code.

Entries are due June 1, The curves are defined by the points xy1 and xy2. This creates one or multiple polygons describing the filled area. By default, the edges connect the given points directly. Use step if the filling should be a step function, i. Define where to exclude some horizontal regions from being filled.

The filled regions are defined by the coordinates x[where]. Note that this definition implies that an isolated True value between two False values in where will not result in filling.

Both sides of the True position remain unfilled due to the adjacent False values. This option is only relevant if where is used and the two curves are crossing each other. By default, the nodes of the polygon defining the filled region will only be placed at the positions in the x array. Such a polygon cannot describe the above semantics close to the intersection. The x-sections containing the intersection are simply clipped. Setting interpolate to True will calculate the actual intersection point and extend the filled region up to this point.

Define step if the filling should be a step function, i. The value determines where the step will occur:. A PolyCollection containing the plotted polygons. All other keyword arguments are passed on to PolyCollection. They control the Polygon properties:. In addition to the above described arguments, this function can take a data keyword argument.The gradient is computed using second order accurate central differences in the interior points and either first or second order accurate one-sides forward or backwards differences at the boundaries.

The returned gradient hence has the same shape as the input array. Spacing between f values. Default unitary spacing for all dimensions. Spacing can be specified using:. If axis is given, the number of varargs must equal the number of axes. Default: 1. Gradient is calculated using N-th order accurate differences at the boundaries.

A set of ndarrays or a single ndarray if there is only one dimension corresponding to the derivatives of f with respect to each dimension. Each derivative has the same shape as f. Assuming that i. By substituting and with their Taylor series expansion, this translates into solving the following the linear system:. The resulting approximation of is the following:. It is worth noting that if i. Spacing can be also specified with an array that represents the coordinates of the values F along the dimensions.

For instance a uniform spacing:. For two dimensional arrays, the return will be two arrays ordered by axis. In this example the first array stands for the gradient in rows and the second one in columns direction:. The axis keyword can be used to specify a subset of axes of which the gradient is calculated. Spacing can be specified using: single scalar to specify a sample distance for all dimensions.

N scalars to specify a constant sample distance for each dimension. New in version 1.
