I would like to know and apply different options with the tool

**"GetDist"**

**1)**First, I would like to put the legend manually on (x,y) coordinates on the figure "

**triangle_plot**"

I give you an example of code snippet abou this request :

Code: Select all

```
# Example of pre-defined location for legend
# Mean of each cosmo parameters : respect order of generated "Big" Fisher matrix
mean = [0.32, 0.05, -1.0, 0.0, 0.96, 0.67, 0.815]
# Names and labels
names = ['Omega_m', 'Omega_b', 'w_0', 'w_a', 'h', 'n_s', 'sigma_8']
labels = [r'\Omega_{m}', r'\Omega_{b}', r'w_{0}', r'w_{a}', r'h', r'n_{s}', r'\sigma_{8}']
matrix1 = GaussianND(mean, COV_Fish_GCs_GCp_WL, labels = labels, names = names)
matrix2 = GaussianND(mean, COV_Fish_GCs_GCp_WL_XC, labels = labels, names = names)
# Plot triplot
plt.rcParams['text.usetex'] = True
plt.rc_context({'axes.autolimit_mode': 'round_numbers'})
g = plots.get_subplot_plotter()
g.settings.figure_legend_frame = True
g.settings.legend_fontsize = 24
g.settings.axes_labelsize = 24
g.settings.axes_fontsize = 14
g.settings.alpha_filled_add = 0.9
g.settings.title_limit_fontsize = 18
#g.settings.plot_meanlikes = True
g.triangle_plot([matrix1, matrix2],
names,
filled = True,
legend_labels = ['Sum GCs + GCp + WL', 'GCs + (GCp + WL + XC)'],
#legend_loc = 'upper right',
contour_colors = ['green','darkblue'],
#title_limit=1
)
```

:#legend_loc = 'upper right'

**Can I put the legend manually by specifying the (y,x) coordinates ? If this is possible, could you tell me how to achieve it ?**

**2)**

**Secondly, I would like to make display on (x,y) axis (xtick/ytick) labels for each sub-plot the value of the "center" of parameter that I plot**(I think I can say

**this center corresponds to the mean of concerned parameter**).

Here below an example which illustrates the

**strange behavior**: for all parameters of the triplot

**except for "h", "n_s" and "sigma8"**, this center value is well displayed. For "h", "n_s" and "sigma_8", the ticks are plotted such a way that we don't have a center value (maybe I have to increase the number of ticks, I don't know ...) :

**3)**Moreover, you can see also that on horizontal axis (x),

**the labels of paramters are not all aligned, depending of the number of decimals with the rotated value of ticks labels values.**

How can I fix this and

**make all the latex symbol aligned (the issue only occurs on horizontal)**, i.e at the same height regards to the (Ox) axis.

For example, can I force the same number fixed of decimals for all parameters ticks values ?

**4)**You will remark that "minus" sign is too long : I suspect it is responsible of bad alignement of [math] parameter compared to all other ones. I wonder how to render,

**in Latex integrated into GetDist, a "minus" sign with a length less large**.

This equest 4) is also connected to the previous request 3) above but in request 3), there is also the varying number of decimals which is involved.

**5)**Finally, I have a last question : each sub-plot has a nice rendering

**but I would like to zoom each joint distribution in order to avoid, as much as possible, empty space around the contours**: is it possible

**to apply a scale factor for each subplot to fill almost the 2D contours**(for example, width and height of contours would fill 90% or 80% of the width/height of the sub-plot) ??

Sorry if my post is a little long, I don't want to be boring but I would really appreciate if some of you could give answers or partially answers

Kind regards
