![]() The last few parameters embed_json, json_prefix, save_path, load_path are used if the user wished to export some of the data into json files to accompany with the html file that the html file will know to interact with. ![]() In such widgets, the system need to know where to put the ticks in which the slider will stop - max_opts defines exactly that. Max_opts is a parameter that is relevant to continuous widgets such as sliders where the user did not define the ticks as we explicitly defined in the example above. This relates to the first two questions the user needs to consider we listed above.īefore continuing to discussion about the third question, lets review the last few parameters: So the user has to be aware of limitations of the save command. And if we try to generate two tabs each with a plot with 20 ticks per slider we will have 20^6 =64000000 states, which will not be reasonable to compute on one computer since it will take a long time - estimated as about half a year of computation assuming there is a strong enough computer with sufficient memory to finish the computation and the file generated is estimated to be around 180 Gb in size. In this case, there are 5x5x5 states for the first tab and 5x5x5 for the second tab altogether 5^6 = 15625 states, which can take an hour to generate and the file will be bigger. For example, the problem becomes worst when you create 2 panel layout tabs each hosting a plot generated by the original states sine example. ![]() So the user needs to be aware of the size of the file to be generated. Due to the exponential nature of combining states from different widgets, this can quickly become unreasonable, therefore the need of a warning. The reason the warning is there is to make sure that the time an file size are reasonable and prevent the user from running long inefficient processes - for example, to generate the file with 8000 states, it will take about half an hour and the file would be about 23Mb in size. And if we increase the number of ticks in all sliders to 20 we will get 20x20x20 =8000 image/states - which will trigger a warning by default - unless we set max_states to be greater than 8000, in which case the warning will disappear. If we increase the number of ticks in the frequency slider to 20, then we will have 20x5x5 = 500 images / states which will take less than a minute to create a file of size 2,6Mb. So each possible image represent a state. However, lets look at what we are doing here, there are 125 images that represent the plot - one for each tick combination of any of the sliders. It will take a few seconds to generate and the file size would be ~1.5Mb - it will smaller without resources included. In this situation there are 5x5x5=125 states. Pn.pane.HoloViews(hmap).save('test', embed=True, resources=INLINE) Hmap = hv.HoloMap(curve_dict, kdims=).opts(height=500,width=500) Return hv.Points(data, kdims=)įrequencies = Ĭurve_dict = Imagine you create a HoloMap with 3 dimensions using the code below import holoviews as hv Yet from version 0.8 it just gives a warning when a user passes a certain number of states - the default is 1000. In the past is was used to block the user from generating huge files that take hours to generate. Max_states is a number that defines when a warning appears when creating a plot. ![]() How much time it will take to construct your file ?.How big you want the generated files to be ?.However, when using embed = True, there are a few things to consider. So to make the html interactive, one will need to use embed=True - in which case, the html file will include JavaScript code to make it interactive. If embed=False then the html document created will not be interactive, for example, if you have a HoloMap with a slider, then the slider will not change the plot. Template and template_variables are a template html file and variables to pass to that template as explained hereĮmbed is a key parameter. The natural use of this by using resources = INLINE after from bokeh.resources import INLINE This makes the html file larger, yet it can work locally and independently. Resources is used when you want your html file to be static and work offline without need to reach out to the internet to grab functions needed to display the interactive part. Title is the tab name that will appear int he browser - the window title - of not changes, it will be called panel Max_opts=3, embed_json=False, json_prefix='', save_path='./',įilename is the file you are saving to -if you do not define a suffix, it is assumed to be html by default, as we will discuss here. Template_variables=None, embed=False, max_states=1000, Since HoloViews save uses the panel save function, we will review the parameters of the save method in panel: save(panel, filename, title=None, resources=None, template=None, First, lets review ways that a file can be created using save.
