How to decrease large error bars
WebThe errorbar sizes: scalar: Symmetric +/- values for all data points. shape (N,): Symmetric +/-values for each data point. shape (2, N): Separate - and + values for each bar. First row contains the lower errors, the second row contains the upper errors. None: No errorbar. All values must be >= 0. WebJan 3, 2024 · If the bar is smaller, lower the std and lower the spread of data which means that data is concentrated around mean and if the bar is larger, larger the std and larger the spread of data.
