+
+````{tab} Overview
+
+The [`LMFit Dialog`](/api_reference/_autosummary/bec_widgets.widgets.lmfit_dialog.lmfit_dialog.LMFitDialog) is a widget that is developed to be used togther with the [`BECWaveformWidget`](/api_reference/_autosummary/bec_widgets.widgets.waveform.waveform_widget.BECWaveformWidget). The `BECWaveformWidget` allows user to submit a fit request to BEC's [DAP server](https://bec.readthedocs.io/en/latest/developer/getting_started/architecture.html) choosing from a selection of [LMFit models](https://lmfit.github.io/lmfit-py/builtin_models.html#) to fit monitored data sources. The `LMFit Dialog` provides an interface to monitor these fits, including statistics and fit parameters in real time. 
+Within the `BECWaveformWidget`, the dialog is accessible via the toolbar and will be automatically linked to the current waveform widget. For a more customised use, we can embed the `LMFit Dialog` in a larger GUI using the *BEC Designer*. In this case, one has to connect the [`update_summary_tree`](/api_reference/_autosummary/bec_widgets.widgets.lmfit_dialog.lmfit_dialog.LMFitDialog.rst#bec_widgets.widgets.lmfit_dialog.lmfit_dialog.LMFitDialog.update_summary_tree) slot of the LMFit Dialog to the [`dap_summary_update`](/api_reference/_autosummary/bec_widgets.widgets.waveform.waveform_widget.BECWaveformWidget.rst#bec_widgets.widgets.waveform.waveform_widget.BECWaveformWidget.dap_summary_update) signal of the BECWaveformWidget to ensure its functionality. 
+
+
+## Key Features:
+- **Fit Summary**: Display updates on LMFit DAP processes and fit statistics.
+- **Fit Parameter**: Display current fit parameter.
+- **BECWaveformWidget Integration**: Directly connect to BECWaveformWidget to display fit statistics and parameters.

+````{tab} Connect in BEC Designer
+The `LMFit Dialog` widget can be connected to a `BECWaveformWidget` to display fit statistics and parameters from the LMFit DAP process hooked up to the waveform widget. You can use the signal/slot editor from the BEC Designer to connect the `dap_summary_update` signal of the BECWaveformWidget to the `update_summary_tree` slot of the LMFit Dialog.

+```{figure} /assets/widget_screenshots/lmfit_dialog_connect.png

+````{tab} Connect in Python
+It is also possible to directly connect the `dap_summary_update` signal of the BECWaveformWidget to the `update_summary_tree` slot of the LMFit Dialog in Python.
+
+```python
+waveform = BECWaveformWidget(...)
+lmfit_dialog = LMFitDialog(...)
+waveform.dap_summary_update.connect(lmfit_dialog.update_summary_tree)
+
+```
