Description
Describe the bug 🖍️
A clear and concise description of what the bug is.
There is special handling to correctly downsample hovertext, marker_size, and marker_color. But we do not downsample marker symbol!
Reproducing the bug 🔍
Please provide steps & minimal viable code to reproduce the behavior.
Giving this information makes it tremendously easier to work on your issue!
A trace like this is incorrectly downsampled:
from plotly.subplots import make_subplots
import plotly.graph_objects as go
x = np.arange(20_000)
y = (3 + np.sin(x / 200) + np.random.randn(len(x)) / 10) * x / 1_000
trace = go.Scatter(
x=x,
y=y,
name='foobar',
showlegend=True,
mode='markers',
marker={
'symbol': np.where(x % 2 == 0, 'triangle-up', 'triangle-down'),
'color': np.where(x % 3 == 0, 'green', np.where(x % 3 == 1, 'red', 'blue')),
'size': 20
}
)
from plotly_resampler import FigureResampler, FigureWidgetResampler
fig = go.Figure(trace).update_layout(height=700, width=1200)
z = FigureWidgetResampler(fig)
z
Expected behavior 🔧
Please give a clear and concise description of what you expected to happen.
When zooming in, marker symbol should be correctly displayed. Instead, when we zoom in, markers are randomly downsampled.
Screenshots 📸
If applicable, add screenshots to help explain your problem.
Panning around when zoomed in but still resampling causes these markers to change symbol randomly, e.g., see the two blue markers around x=18.6k
