Having issues with chaining the font size of the title in the plot_gate function.

[javisolivan]

I am working to generate plots for fcs files that I have generated. I am tying to export high resolution images but to do so I need to increase the font size. When doing so, all the fonts respond except the sample and gate path of my plot. I there a way to have the top middle text in the plot_gate function also increase in size?

Here is the code I am using:

`
output_notebook()
png_files = []
for index, den_sample_id in enumerate(wsp.get_sample_ids(group_name='All Samples')):
p = wsp.plot_gate(den_sample_id, 'ChgA_Pos',x_min=0, x_max=1, y_min=0,y_max=1, bin_width=4)

p.toolbar_location = None
p.title = None
p.plot_width = 1500  # Adjust this value as needed
p.plot_height = 1500  # Adjust this value as needed
p.xaxis.axis_label_text_font_size = '32pt'
p.yaxis.axis_label_text_font_size = '32pt'
p.xaxis.major_label_text_font_size = '32pt'
p.yaxis.major_label_text_font_size = '32pt'

sample_results = wsp.get_gating_results(den_sample_id)
percentage_gated = sample_results.report[sample_results.report['gate_name'] == 'ChgA_Pos']['relative_percent'].iloc[0]
# Annotate the Bokeh plot with the percentage
percentage_label = Label(x=45, y=418, x_units='screen', y_units='screen',
                         text=f'{percentage_gated:.2f}%', render_mode='css')
p.add_layout(percentage_label)
# Export the individual plot to high-resolution PNG
png_filename = f"plot_{index}.png"
export_png(p, filename=png_filename, width=1500, height=1500)
png_files.append(png_filename)

with PdfPages('combined_plots.pdf') as pdf:
for png_file in png_files:
img = plt.imread(png_file)
plt.figure(figsize=(15, 15))
plt.imshow(img)
plt.axis('off') # Turn off axis numbers and ticks
pdf.savefig() # saves the current figure into a pdf page
plt.close()
`

Hi,

It's kinda hidden but the titles are placed in a layout named above, and they can be accessed using p.above. The FCS file name is in a Title object in the 2nd element. To change the file name's font size:

p.above[1].text_font_size = '1.5em'

Hope this helps!
