doing aspect_ratio=:equal doesn't seem to work

[slack] <rveltz> Hi,

I would like to do a isosurface in GR. So far so good but:
• how can I specify the number of levels? (levels = 3?
• how can I zoom out (I see rotation, tilt but not the radius
Thank you a lot for your help

Josef Heinen

@jheinen

Are you using plain GR or the gr backend in Plots?

In plain GR, you can only specify an isovalue (= threshold)

@GitterIRCbot

[slack] <rveltz> I am using GR

[slack] <rveltz> but how can you zoom out?

[slack] <Misha Mikhasenko> Are there any dirty hacks to put the cross of errorbar to the legend?: https://files.slack.com/files-pri/T68168MUP-F01C10U9WER/download/image.png

@GitterIRCbot

[slack] <Misha Mikhasenko> Are there any hacks to put the cross of errorbar to the legend with Plots/pyplot?

BridgingBot

@GitterIRCbot

[slack] <nils.gudat> I guess you could scatter with a cross marker and just put it outside the bounds of the visible area? Example:

```julia> scatter(rand(10))

julia> scatter!([0],[-1], marker = :cross, label = "Standard error", ylim = (0.0,1.0), color = "black")```

[slack] <Misha Mikhasenko> good idea. althogh looks a bit different: https://files.slack.com/files-pri/T68168MUP-F01CUAVSX32/download/image.png

[slack] <Misha Mikhasenko> good idea. although looks a bit different

[slack] <Misha Mikhasenko> :+ does pretty well

[slack] <Misha Mikhasenko> It is so annoying to open the picutre in inkscape and manually modify 😩

BridgingBot

@GitterIRCbot

[slack] <Misha Mikhasenko> Is there a way to change the series order in the Plot{Plots.PyPlotBackend() n=9} object?

[slack] <Misha Mikhasenko> ```p = make_myplot() # Plot{Plots.PyPlotBackend() n=9}
pp = p[1] # Subplot{1}
plot(pp)

ERROR: Cannot convert Plots.Series to series data for plotting```

@GitterIRCbot

[slack] <Misha Mikhasenko> I have two plot and would like to add a line (one series) from the first plot to the lowest layer of the second plot.

p1 = make_first_plot()
p2 = make_second_plot()
plot(p1[1][1][:x], p1[1][1][:y], lab="model")
plot!(sp=1, p2) # replace p1
plot!(sp=1, p2) # also replace p1

[slack] <loki._.> A user recipe can take arbitrary keyword arguments and process these

BridgingBot

@GitterIRCbot

[slack] <nils.gudat> So should I basically have one big

@recipe function f(s::MyStruct; type = "main_results")
    if type == "main_results"
        [first type of plot]
    elseif type == "uncertainty"
        [second type of plot]
    end
end

BridgingBot

@GitterIRCbot

[slack] <nils.gudat> Seems to do the trick!

BridgingBot

@GitterIRCbot

[slack] <mkborregaard> or define a seriestype

[slack] <mkborregaard> given that you are not using dispatch anyway

Hi. I have a question about 3d plots. How do I make the ticks and labels for the 'z'-axis to be drawn on the left instead of on the right? I am trying to do it with it pyplot backend.

gideonsimpson

@gideonsimpson

hi, i have a problem that the tick labels on my color bar are partially cut off because i used larger font sizes. how can I extend the figure size so they're fully rendered?

BridgingBot

@GitterIRCbot

[slack] <loki._.> you can set the figure size with size = ( width, height )

BridgingBot

@GitterIRCbot

[slack] <daschw> Or you could increase the margin, like e.g bottom_margin = http://5Plots.mm , you have to find the value and unit that fits your needs.

hey guys, any idea on how to decrease the padding between multiple subplots in a layout?

BerndR

@bernd1995

Hey guys, is it somehow possible to 'load' a previously created plot again into julia and retrieve data like x-, y- and z-components?
In particular I would be interested to do this for a *.html file created with the plotly-backend.

Hello, how could I plot negative numbers with log10? I have

@df df_final_biomass_diff_array_fw_10_industry_high scatter(:body_mass_fw_1,:bio_diff_S33_1, xaxis = :log10, yaxis = log10.(:bio_diff_S33_1 .+ 10))
Which works, but then the yaxis disappears.

I am using Plots with Julia 1.5

Roman Bange

@rbange

@HelgavonLichtenstein obviously you cannot simply calculate the log10 of negative values, thats why Plots fails to do this

had the same issue a while ago

i modified my data by applying a log-modulus transformation beforehand https://blogs.sas.com/content/iml/2014/07/14/log-transformation-of-pos-neg.html

HelgavonLichtenstein

@HelgavonLichtenstein

Yes, I understand, but I try to make the values positive by adding 10 to the yaxis

A MWE

x = -10:0.01:10
y = x
plot(x, y)
plot(x, y, yaxis = log10.(y .+ 100))

It works, but the scale disappears from y

Roman Bange

@rbange

Ah i see

HelgavonLichtenstein

@HelgavonLichtenstein

I like this log-modulus transformation you shared

Roman Bange

@rbange

Its nice as you can boundlessly plot negative to positive values

I also tested the sample you shared, it does work as expected, but yaxis = log10.(y .+ 100) only yields values from 1.95 to 2.04 so its a straight line

Maybe the yaxis is displayed, but outside of the value space? Meaning y samples are distributed e.g. 0-100, but the yaxis is shown at e.g. y=300

HelgavonLichtenstein

@HelgavonLichtenstein

How do you change the value space?

Roman Bange

@rbange

Guess its fitted to the given data

i think the proper solution is

@df df_final_biomass_diff_array_fw_10_industry_high scatter(:body_mass_fw_1,log10.(:bio_diff_S33_1 .+ 10), xaxis = :log10)

HelgavonLichtenstein

@HelgavonLichtenstein

Neato, using the log-modulus transformation it looks like

@df df_final_biomass_diff_array_fw_10_industry_high scatter(:body_mass_fw_1, sign.(:bio_diff_S33_1).*log10.(abs.(:bio_diff_S33_1).+1), xaxis = :log10)
