# 1. Generate some 2D scalar data (e.g., a sample gradient)
# A false color image is an image that depicts an object in colors that differ from those a photograph would show.
# data = np.random.rand(10, 10) # 10x10 array of random values

folders="20260123vShift_0_LVA_0p6IClamp_amp_index"
template=folders+"*/ca_suppr/delta_ca_total_mean.txt"
files=glob.glob(template)
locations=np.loadtxt(folders+"0/ca_suppr/v.txt") # v.txt contains dendritic locs
v_per_index=[v for v in range(-70,-58, 2)]

data=np.zeros((len(v_per_index), len(locations)))

for file in files:
    index=int(file.split('index')[1].split('/')[0]) # finds the amp_index
    data[index,:]=np.loadtxt(file)

# Alternatively, a sample gradient:
# x = np.linspace(0, 10, 100)
# y = np.linspace(0, 10, 100)
# X, Y = np.meshgrid(x, y)
# data = np.sin(X) * np.cos(Y)

# 2. Display the data as a false color image
plt.figure(figsize=(7, 5))
# Use 'viridis' colormap as an example. Matplotlib has many other options.
# The input is 2D scalar data, which will be rendered as a pseudocolor image.
plt.imshow(data, cmap='YlOrRd', interpolation='nearest') # 'nearest' avoids int

# 3. Add a colorbar to show the value-color mapping

plt.colorbar(label='$\Delta{Ca}^{2+}(\%\ Baseline)$')
# 4. Add titles and labels
plt.title('Figure 2B')
plt.xlabel('Apical Location ($\mu$m)')
plt.ylabel('Vm (mV)')
