Creating Events allows you to record data to be shown on your roast graph with either Buttons or Sliders.
Artisan’s standard buttons are as follows:
The buttons above contain key time points in your roast and after using the trier in the roaster, you would push the button when the event occurs. Pushing these buttons during a roast will add data to your roast log. You can find the data under Roast>Properties>Data tab.
Sliders can be used to create Events as well. The sliders appear on the left side and can be used to input a variable value between 0 and 999. Make sure you check Decimal Places under Curves>UI if you use them. Your events will be rendered on your graphs (if you have the Events checked on the Sliders tab) with the first letter of the name of the event and two decimal places. So Gas at a value of 35 would be G35. Or if you don’t check decimal places G3.
You can define up to four custom Events such as Gas and Airflow. Red buttons are Gas readings on propane and the Blue are Fan settings in the example below.
And here is what a slider looks like. NOTE if you have sliders checked on the config tab the initial value will be recorded into Artisan at the start of the roast:
In order to set up custom events, you need to create Event types, under Config>Events:
You can label up to 4 event types. You can edit how they work with the tabs Buttons and Sliders. When you click a button or move a slider Artisan records an event on a scale of 0-999. You can display these events on your roasting graph. You may need to set your temperature axis to a low of 0° in order to see these the best. Config>Axes. If you check Mini Editor you will be able to add or edit existing events during the roast. It will appeal below your Buttons.
You have the option to render event descriptions instead of values. Use the event button type “–” that creates an event adding labels to the graph rendering its button description. For those using sliders the rendering will continue to be the first letter of the Event name and two digits of the value IF you check Decimal Places under Config>Curves>UI. If you don’t it will render only one digit.
During a roast it is now possible to have Artisan draw a line at the current point in time, which helps to compare the current roast state with that of the template (RoR, background event markers,..). You can activate this feature in the Events dialog (menu Config » Events) by ticking the flag Show Time Guide. This helps you see Events you have in your Background roast profile.
Rendering Events on Your Curves
To see the values of the TP, DE, FCs etc, check the box for Annotations. For Events that you have defined, you will see to the right of Events a dialog box with drop down options:
Flag will render an event either on your ET line or your BT line (check the box “show on BT”) and your event description if you check the box for Descr. (number represents how many letters) or it will show the first letter of your event name and the event value if you do not.
Bar will show you a multicolored bar at the bottom of your graph with the first letter of your event name and the event value. Description is not relevant.
Step will show you a plot (step) graph with no values.
Step + shows you a plot graph plus your descriptors on the BT line (same choices as under Flag)
Combo shows you a plot graph with the descriptors on the plot (step) graph.
Here are examples:
You are also now able to add an event type that will show on the graph when you hit the event button. With this new button type, you can define a button that will add an event item labeled with the description that shows up on the graph. You could record when you take a sample from the trier as an example.
Buttons Configuration Sample
The above screenshot shows the Button Label and Description, Type, Value, Action, Documentation, Visibility, Color and Text Color. The Label is what shows on the button. The Description is what shows on the graph. The Value is from 0-100. So you have to adjust your scale to that. For example if you are using 2.0-3.5kPa for gas you might have values 20-35. You can choose the button to trigger a machine control action such as change the Hottop heater. You can have the buttons visible or not and choose their color and text. New in 1.4 you can now make inserts to the table which is very helpful when you decide you need to add a button for a value in between two existing values.
Note in particular the Automation check marks at the bottom. If you want the event Charge to be automatically recorded, you need to press Start and let it be on for 5x your sampling rate in order to have AutoCharge work properly. So for a sample rate of 3, don’t charge the roaster until at least 15 seconds after you push Start.
Sliders Configuration Sample
Min and Max are the key settings. The factor and offset are used to convert dial settings by advanced users to linear output.
Quantifiers turn readings received from a connected device into custom events on their 0-100% scale. For example, if you have a channel configured to read burner output on a scale from 0-2000 you can decide to hide the corresponding curve (as it won’t fit into the range of the standard temperature axis) or turn just the changes of its readings into events by defining a corresponding quantifier. You end up with a more readable and useful profile.

You can create multiple palettes of buttons as well to use in different roasting situations.
