Gnuplot cb label position

I would like to place a boxed label near the lower left corner of the plot canvas, and I'd like the contents of the box to be centered.

Is this possible without knowing in advance how wide or how high the box will be? In the development version version 5. The release version 5. In either case the "boxed" option can be specified for individual labels or for "plot Thanks for the reply. I'm trying to put a boxed label outside the actual data plot, in the lower left corner of the plot canvas. The set label command has options for left,center,right, but whichever is chosen seems to be dual purpose.

That's ok, unless one wants to put the label near an edge of the plot canvas. Use left-justified text if you want it to hug the left edge of the canvas, and right-justified text if you want it to hug the right edge. Here's a junk plot just to show a label in the lower left, produced with. Thanks for the suggestion.

My label has three lines of text, so I would like to stick with the center option maybe I'm just being too picky. In this application it will always be three lines. The width will be variable, but not so much that I can't live with hardcoding the position values. So that's what I'll do. I can't tell you how pleased I am I can finally do real 3d graphs in Excel. Lotus could do it over 25 years ago. It's a shame Microsoft has never added this, and probably never will. Could be a case of market dominance leading to brain damage.

If you use a grid it can happen that you want to use a white background with your labels. This would improve the readability of the labels as it reduces interaction with the grid. To add a background is not straightforward, especially if you have rotated labels. In the following, we will have a look how to solve the problem for LaTeX terminals. Thanks to V. Click on the figure to see the original PDF version. To add a background to the labels we use the colorbox command, which we include in our terminal definition via the header option.

If you have a label with a line breakyou have to decide if you want to apply the background to every part of the line break, as shown in Fig.

If you want to put labels into a graph using the epslatex terminal you are probably interested in using a smaller font for these labes than for the rest of the figure. An example is presented in Fig. Figure 1 shows again the photon flux density from one of the last postsbut this time plotted with the epslatex terminal. First we introduce a abbreviation for the font size by adding a command definition to the header of our latex file.

But as an author of the figure you have to find space to place the labels in the figure, and it could be that you have to rotate the labels to stick them to the lines.

Figure 1 shows the theoretical curves of photon flux density dependent on the photon energy for different characteristic tail state energies E0. E0 is an indicator for disorder in a crystalline system. To reduce the amount of trail and error for placing the E0 labels, we get the rotation directly from the data by fitting a linear function to the corresponding part of the data.

It is a little bit tricky, because we have a logarithmic y-axis. The first bracket is the range on the x-axis and the second sets the corresponding y range to auto.Gnuplot uses four coodinates to define positions of arbitrary lines, arrows, texts, and a legend. Those are called as "first", "second", "graph", and "screen".

The "first" coodinate is the left Y-axis and the bottom X-axis. The "second" is the right Y2-axis and the top X2-axis. The "graph" coodinate is a relative position in the graph frame.

The "screen" coodinate is a relative position in the whole screen paper. The defaut is the "first" coordinate. The position can be specified by the syntax graph x, screen y. The "first" label is placed at the center of the graph. The origin of the graph coordinate locates at the left bottom corner.

The top right corner is the coordinate 1,1. The location defined in the graph coordinate is relative to the graph size. For example graph 0. The origin of the "screen" coordinate is the left bottom corner and 1,1 is the top right corner of the screen paper.

This coordinate is not affected by the size of plot. A label defined in the "first" coordinate moves when the range of X and Y axes are changed, but it does not move if the coordinate is "graph" or "screen". Let's move the whole graph toward right and top. The command set origin x,y changes the origin of the graph. The x and y are given in the "screen" coordinate.

The origin given in the screen coordinate is always left bottom, but the origin of the graph coordinate moves when origin is changed. To explain something, an arrow is often used in a figure. Gnuplot makes arrows or lines by set arrow command. The simplest syntax is set arrow from 1,2 to 2,4which shows an arrow from 1,2 to 2,4.

The coordinate is the "first" coordinate if it is not specified, so that the location depends on the X and Y axis values. To make arrows independently of the axes, use the graph or screen coordinates. Gnuplot assigns an integer number for each arrows if not specified. The first one is "1" and the second is "2", so on. Those numbers are used to redefine the arrow or remove it. The syntax is the same as set label command.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

You can use a Gnuplot script to place your labes interactive by hand and get the corresponding label position coordinates. To give you a clue how it functions, have a look at this video:. Download video. The Gnuplot code to generate this video is stored in two files. One normal Gnuplot file for plotting the points, using a technique presented in the Plotting single points entry. At the end of the file, after the plot command another Gnuplot file is called with the label to place.

Also the set mouse command enables the use of the mouse for our interactive purposes. A label is added or placed at a new position as long as the left mouse key is clicked. If the right mouse key or any other key is pressed the label is positioned at the last chosen position.

This position is also printed to the standard output every time a new position is chosen. If you want to position the center of the label at the mouse position, you can change the set label line to. Tags: interactivelabel. Name required. Mail will not be published required.

You can change the position with the set key command.

If you give the command. Available options are, left, right, top, bottom, outside, and below.

You can combine some of them. For example, outside bottom. It is possible to set the position of legend directly. The coordinate is the system defined by the X and Y axes.

If you want to place the legend independently of the axes, see coordinate. When one plots data with error bars, the error bar also appears in the legend see the figure below. However, even if the data have errors in the Y-direction, the error bar in the legend becomes horizontal one, and usually we do not need such an error bar.

Here is a simple way to remove the error bar in the legend. For example, you may have an extra white-space at the left side even though you want to place the legend just next to the Y-axis with the command set key left.

To adjust the location of the legend containing postscript symbols, you have to give its coordinate directly. You can change the line-skip in the legend with set key spacing command. To make the skip 1. To make a frame-box around the legend, use set key box. The line-kind for the box is the same as the frame of the graph. You can change this by providing the box keyword followed by an index of the line-kind.

Otherwise you can define the linestyle as:. About Legend There are two ways. How do I get rid of error bars in a legend? When we plot the next data test. Location of the text is sometimes strange when Postscript symbols are used in it.
