Isospace Plot Output Axis

[mjeanfin]

Hello,

I am trying to use a MixSIAR figure for a poster and one of my committee members has a problem with the x and y axsis intervals of the isospace plot. I have modified the ggplot object as posted in #220 and #222 but cant find a way to set axis limits or modify them in any way. I'm still very new at R so I might have missed something.

Load mix data

mix.filename <- file.path("C:/Users/miche/OneDrive/Documents/MixSIAR Plots 04022023/Plot_Site_Habitat_BR/Consumer_Data_Sheet_2020.csv")

mix <- load_mix_data(filename=mix.filename,
iso_names=c("d13C","d15N"),
factors="Taxa",
fac_random=FALSE,
fac_nested=FALSE,
cont_effects=NULL)

Load source data

source.filename <- file.path("C:/Users/miche/OneDrive/Documents/MixSIAR Plots 04022023/Plot_Site_Habitat_BR/BR_Habitat_Source.csv")
source <- load_source_data(filename=source.filename,
source_factors=NULL,
conc_dep=FALSE,
data_type="raw",
mix)

Load discrimination/TDF data

discr.filename <- file.path("C:/Users/miche/OneDrive/Documents/MixSIAR Plots 04022023/Plot_Site_Habitat_BR/BR_TEF.csv")
discr <- load_discr_data(filename=discr.filename, mix)

Make isospace plot

plot_data(filename="isospace_plot_Fish2020_BR_04042023",
plot_save_pdf=FALSE,
plot_save_png=TRUE,
mix,source,discr,
return_obj=F)

new, returns ggplot object

g = plot_data(filename="isospace_plot_Fish2020_BR_04042023_gg", plot_save_pdf=F, plot_save_png=F, mix,source,discr, return_obj=T)

now modify plot using ggplot2 commands

png("isospace_plot_Fish2020_BR_04042023_gg.png",width=7, height=7, units="in", res=300)
g + theme(panel.border = element_blank(), panel.background = element_blank(),
panel.grid.major = element_blank(), panel.grid.minor = element_blank(),
axis.line = element_line(colour = "black"),
axis.title=element_text(size=20), axis.text=element_text(size=14),
legend.text=element_text(size=12), legend.title=element_text(size=14))
dev.off()
