I have a linear Bokeh plot under Bokeh version 3.3.0. I would like to add a (scatter) plot on an additional x-axis with logarithmic scale. This is my code: import pandas as pd from bokeh.plotting import figure, show, ColumnDataSource from bokeh.layouts import gridplot from bokeh.models import LogAxis, LinearAxis, Label, LabelSet, Title, Range1d # A simple dataframe with time, UTCs, altitude and two columns of imaginary data df = pd.DataFrame([['2024-06-21 06:22:38', 605.968389, 0.994548, 3], ['2024-06-21 06:22:39', 616.009398, 0.983443, 4], ['2024-06-21 06:22:40', 624.630573, 0.973647, 1], ['2024-06-21 06:22:41', 633.476367, 1.017651, 2], ['2024-06-21 06:22:42', 642.322161, 5.017651, 2], ['2024-06-21 06:22:43', 650.268389, 30.726555, 4], ['2024-06-21 06:22:44', 659.559398, 89.2359, 5], ['2024-06-21 06:22:45', 665.630573, 6.92018, 3], ['2024-06-21 06:22:47', 673.476367, 0.69398, 2], ['2024-06-21 06:22:48', 685.322161, 0.770802, 1], ['2024-06-21 06:22:49', 697.155939, 0.856488, 0], ['2024-06-21 06:22:51', 716.763057, 0.934408, 3], ['2024-06-21 06:22:52', 722.012345, 7.865522, 2], ], columns=['time', 'Altitude', 'log_data', 'linear_data']) #Linear Plot with second x-axis in logarithmic scale p = figure(title="Combined linear / log x-axes", x_axis_label="Linear Data", y_axis_label="Altitude / km", x_axis_type='linear', frame_height = 900, frame_width = 650, ) p.xaxis.axis_label_text_color = "red" # linear data p1 = p.line('linear_data', 'Altitude', line_color='red', line_width=2, source = df) # log data p.add_layout(LinearAxis(x_range_name = "x2", axis_label="Log data", axis_label_text_color='blue',), 'below' ) p2 = p.scatter('log_data', 'Altitude', line_color='blue', line_width=2, x_range_name = 'x2', source = df) # Range of additional x-axis: p.extra_x_ranges = {"x2": Range1d(start = 0, end = 115), } # Graphical output: layout_p = gridplot([p], ncols=1, width=700, height=900) show(layout_p) I changed LinearAxis into LogAxis # log data p.add_layout(LogAxis(x_range_name = "x2", axis_label="Log data", axis_label_text_color='blue',), 'below' ) but this caused the second axis to be displayed without any ticks and the scatter plot was still shown on a linear base. Any hint for me? Continue reading...
